13 Claims.

This invention relates to improvements in collapsible camp stoves, particularly those of the kind which are adapted to burn fuel of a solid character, such as charcoal, coke and the like.

One object of the invention is to provide a stove of this character wherein the companion parts such as the sides and ends are counterparts and may be used interchangeably whereby to enable them to be formed by the same dies and to be assembled with facility.

A further object is to provide a collapsible camp stove having foldable legs applied thereto for rigidly supporting the stove when in use and which may be compactly folded when not in use, such legs serving further as handles to facilitate carrying the stove or for dumping its fire-contents.

A still further object is to provide a stove which is so designed that the fuel will burn freely and uniformly, this object contemplating a stove having a substantially horizontal grate and a fire box closed on all sides above the grate.

A still further object is to so design the stove that fuel may be readily introduced into the fire box.

In the accompanying drawings:

Figure 1 is a perspective view of a stove embodying the features of the invention. Figure 2 is a perspective view showing the stove in its folded position. Figure 3 is an enlarged vertical section taken along line 3-3 of Figure 1. Figure 4 is an enlarged fragmentary section taken along line 4-4 of Figure 3. Figure 5 is a similar section taken along line 5-5 of the same figure. Figure 6 is a side elevational view of the stove, the fire box being shown partly in section, and the grid folded back. Figure '7 is a top View thereof with the grid removed. Figure 8 is a fragmentary end view of the pivotally-connected side walls of the fire box in their folded position. Similar characters of reference indicate corresponding parts throughout the several views.

The stove, as illustrated, includes rectangularly-shaped side walls l0 and triangularly-shaped end walls I I which form a substantially V-shaped fire box, the said walls preferably being in the form of sheet-metal stampings. The side walls It! are counterparts. Each is formed with a reinforcing bead I2 along its upper edge, with flanges I3 along its opposite ends and with a flange l4 along its lower edge, the said side Walls being pivotally connected by suitable connecting means I5 which pass through the flanges l3 near their lower ends. The side walls being counterparts, it will be understood that one of the flanges l3 of each wall will fit against the outside of the cooperating flange of the other wall while the other flange will fit against the inside of the cooperating flange. The lower flanges i4 overlap, as best shown in Figure 3, when the stove is opened up for use.

The end walls II are also counterparts. Hence one is pivotally connected to one side wall while the other is connected to the other side wall. For this purpose, one of the flanges l3 of each side wall carries hinge loops Iii which pass through openings ll formed in one edge of the end walls. The other flange of each side wall is preferably formed with a slot l8 to accommodate a tang or latching member l9 which is pressed out of the opposite edge of the end walls. In this connection it will be noted that the openings ll are elongated so that proper displacement of the end walls ll relative to the side walls can be effected to enable the ready insertion and removal of the tangs i9 into and out of their companion slots it.

The end walls I i are truncated. They terminate, therefore, a substantial distance above the lower ends of the side walls, whereby to provide openings 20, as shown in Figure 1, through which air may enter the fire box below the grate. The latter is indicated at 2! and is preferably 7 in the form of a perforated corrugated sheet. It is pivotally connected by strap hinges 22, shown in Figures 3 and 7, and in its operative position is supported in a substantially horizontal plane by flanges 23 which are formed upon the end walls II, the openings 24 and the longitudinal channels in the grate providing for the admission of air to the fire box to create an effective draft and insure a uniform burning of the fuel.

The stove also includes a grid 25 for supporting the cooking utensils over the fire box. As

- shown and preferred, the grid is formed in two sections which are pivotally connected by links 25 so that either section may be opened, as shown in Figure 6, to enable fuel to be introduced into the fire box without disturbing the other section. The said links also enable the sections to be folded upon one another when the stove is not in use, and to be contained between the folded side walls I0. This grid may contain more sections, if desired.

The legs of the stove are indicated at 21 and are so mounted as to be compactly folded when not in 50 use and unfolded to rigidly support the stove for use. Two of them are pivotally connected to each of the side walls l0, one at one end and the other at the other end. The pivots, which are indicated at 28, are adapted to permit swinging movement III ill

of the legs parallel to the side walls I0. Hence, when the side and end walls of the stove are open and the legs are moved to their unfolded or extended positions, the legs carried by one side wall cross those carried by the companion wall as best shown in Figures 1 and 2. A diagonally-extending strap or retainer loop 29 is applied to each side wall adjacent the opposite ends thereof and is associated with each of the legs 21. The said straps extend across the legs in the vicinity of the pivots 28. They are so formed that they provide end shoulders 30 which the legs engage as the latter are extended and just after they pass beyond the vertical or cambered position, as best shown in Figure 6. A teat or projection 3| is formed or provided upon the side walls It) under each of the straps 29. The legs 21 are deflected slightly as they pass over the said projections, the latter being operative to resist return movement of the legs to their retracted positions.

It will be apparent that during movement of the legs to their extended or operative positions, the leg of each crossed pair which is first manipulated will pass beyond the associated projection 31 and engage the shoulder 39 of the asso ciated strap 29. When the other leg is extended, however, the first leg will prevent it from mov ing far enough to engage the shoulder of the strap associated with it, the engagement of the two legs occurring just as the second leg passes over the projection 3| which is associated with it. In other words, each pair of crossed legs is held against movement in one direction by a shoulder 30 of one of the straps 29 while they are held against movement in the opposite direction by one of the projections 3|, the particular shoulder and projection utilized depending upon the order in which the legs are extended. The mounting of the legs in the manner described not only effectually braces the stove when in use so that it will stand firm and rigid, but it has the further advantage that the stove may be picked up and carried by its legs, either to move it from one place to another or to dump the grate, without danger of its collapsing. In their retracted positions, the legs overlie the side walls I!) as best shown in Figure 2, the free end of each leg fitting behind the strap 29 associated with the adjacent leg.

When not in use, the stove is folded up into the compact self-contained unit shown in Figure 2. When it is desired to do this, assuming the grid to have been removed and the grate to have been dumped, the latter is swung upon the hinges 22 to a position against and substantially parallel with the side wall to which the said hinges are secured. Each of the end walls I! is then released and swung to a position against the particular side wall I!) upon which it is mounted. After the grid is folded, it is arranged between the said side walls and the latter are closed so that they are substantially parallel with one another. During this latter operation the flanges M at the lower edges of the side walls separate, as best shown in Figure 8, and permit the discharge of any ashes which may have accumulated under the grate. The retraction of the legs and their arrangement along their respective side walls may be eifected at any stage. When folded in the manner described, the stove is not only compact and self-contained but is of a shape which will enable its convenient storage in a small space. If desired, a pivoted retaining slip or catch 32 may be provided for securely clamping the stove in its collapsed position.

While this improved camp stove is manifestly simple, compact and inexpensive in construction, its structural features assure a wide fire bed and an even distribution of heat without waste of fuel; they provide a separate fire and ash compartment and prevent any sparks or live ashes dropping to the ground, thus eliminating fire hazards; and the fire is fully protected from the wind and the heat is concentrated in such a way 7 that it must pass upwardly through the cooking grid.

In the drawings, the grate 2| is shown as corrugated lengthwise, but, if desired, it may be corrugated crosswise of the stove.
